Would it?
It's present in OpenFirmware too, in all the places it should be
(/pci/isa/serial@2F8 or something, if you set the output to serial
it should be there too, but of course then stdout is serial and
the code below is going to fail :)
Anyway. I am going to attempt to find a Mac I can start building
things on. I always wondered how on earth I could get a FreeBSD
or NetBSD port going when I need a working port on the same platform
to do it. I don't even have a PC I can shanghai for the task right
now.
Do they run in PearPC or so?

That's all present.
What about a text mode (just using stdout to print strings)?
